Your Heart
Theres a way of living that Faery Wicca stresses. The concept of thinking with your heart and feeling with your mind. Your brain is only book smart and retains memories. While your heart is what truly does the thinking. Your heart is what can tell the truth from a lie, and all lies retain a little truth thats hidden. Everyones had that gut feeling where the should've zigged when they zagged. That's not your left side of the brain talking. Thats your heart.
The problem is alot of people don't listen to their heart. They try to think things through rationally and end up falling on their face. In the past, I've had a few people ask me "How can I tell if somethings real?" and always my response is, "In your heart, if it's real, you know it is. If it is real, and your doubting it, your trying to rationalize with your brain."
And by the flip side of the coin, it isn't your heart that feels. That's your brain. Your brain is a receptor to what happens. It can determine pain and pleasure and all other emotions. When an emotionally challenged person is put on medicine they give him stuff for his brain, not his heart. Thats the scientific out look of it. The metaphysical look at it is that the brain visualizes. It creates mental pictures of whats happening and how inside your feeling about it.
The Fae seem to respect those who are able to think with their heart and feel with their mind, as well as someone honoring their word. Fae are very curious beings, but only dare approach someone whose trust worthy with others, and theirselves. But to sum this all up, if you have a gut feeling about something, trust it. And throw rationalization out the window if your confused. Rationalizing it will only confuse you further, and may cause you to deny a faery favor unknowingly granted to you.
